To @ZZ whom it ma concern.'

Be it known t at we, PATRICK F. MAL- l tsr, Aomsox BREWER, and RALPH B. ll-flossen, citizens of the United States, re-

siding in the city andcounty of San Francisco and State of California, have invented new and useful mprovements in Bed- Springs, ott which the following is a speciication.

This invention relates to a bed spring.

The object of the invention is to kprovide a simple, durableA easily asmbled bed spring which .is so constructed that, the

springs arepivotally' interlocked and tied,

both longitudinally and transversely, thereby producing a strong, yieldable support for the mattress.

Another object of the invention is to produce a noiseless hinge connected between theV springs which Will allow every spring to act independently and which will prevent any loose connection or rattling' noises.

. siste of side rails 3 with the connected cross-v Further objects will hereinafter appear.

', Tlie invention consists of the parts andthe construction and combination of parts as hereinafter more fully described and claimed, having reference to the accompanying drawings, in which- Figure 1 is a perspective' view, partly broken away, showingthe connected springs @assembled Fig. 2 is an enlarged perspective view of the lateral hinge connection between the springs. Fig'. 3 is a side elevation of same. Fig. 4 is a detail view of the'longji-4 tudinal connecting wire l2.

Referring to the drawings, A.' indicates in general the base portion of the bed spring, upon which the coils 2 are mounted. and B represents the upper frame, preferably rectangular in shape. The baseV portion is in this instance rigidl;v constructed and conn bars or slats 4 preferably riveted to the side rails, as :it Supported upon the cross-bars of the lower frame is a plurality of coil springs 2, the lower reduced convolutions 6 of which are secured by longitudinally disposed tie wires 7 in the usual manner. rIhe upper or enlarged convolutibn 8 of each coil is projected laterally and bent upon itself to form an arm 9 having a downwardly turned loop l0 on its outer end which is adapted te' engage with and overlap the upper convolution of the adjacent spring and the other side .of the wire forming the specification of Letters sacem.

y arm is returned and secured, as at 1l. The

upper or enlarged convolutionl 8 of each tying the springs together laterally and the loops 10 form one side of a hin e connection. The other side of the hinge is formed by a longitudinall disposed Wire 12 having a plurality of oops 1.3 formed there0'n, as insov dicated in Fig. Il. These loops are inserted between the parallel wires of the arms 9, under the wires 8, through the upper sides of the loops 10, and are then bent down wardly, as indicated sat 14, by a suitable form of tool tosecure them in place. The spacing between the loops 13 is equidistant or equal to the spacing between the centers of the springs and a slight bow is formed between the loops 13, as indicated at l5.

The springs connected as .here shown can be quickly and easily assembled. The lower reduced end of each spring is irst secured to the cross-bar by the tie wire 7 and placed in a position where the arm 9 with the loop 10 will overlap the enlarged convolution of the adjacent spring. The wires 12 are then placed longitudinally of the bed spring in a position where the loops l register with the connected edge for the springs and is further secured to the spring structure by attaching the ends of wires 12 to same, as indicated at 16a. A yieldable interlocking support for. the mattress is thus secured.

The hinge connection, formed by the loops 10 and 13, does not only permit a free movement of each spring, with relation to the connected lateral arm 9, as indicateellmrr. UU

dotted lines 17 and 18, Fig. 3, but it also forms a noiseless hinge, that is, all play or rattling motion between the connected springs and loops is taken up by placing e slight curve or tension in loop 13 when the outer end of same is bent down. as indicated at 14.. This slight curve or tension in theloop casses the wires in same to beary -@freinet wire @en Vvlll thus hold this firmly against the underside of the loop l0 which is slightly bent et 3.9 to form s. hearing for wire 8. Loose connections and the tendency to rattle is thus entirely eliminated and accidental disconnection or displacement is entirely prevented.

By having the several springs united in the manner described a smooth, unobstructed, yielding surface is produced for the reception of a mattress and all possibili- .ties of catching and tearing the cloth of same is prevented.

The materials and finish of the several parts of the bed spring are such as the judgment of the manufacturer may dictate.

Having thus described our invention, what we claim yand desire to secure by lietters Patent is- 1.In a lied spring, a series of coiled springs, a laterally extending arm on the upper convolution of each spring engaged with one side of the upper convolution of the adjacentv spring, and a wire engaged with the arm at' spaced points located on opposite sides of the part of the upper convo lut-ion ot `the adjacent spring engaged by said arm and disposed on theopposite side ot said arm-engaged part of the upper convolution of the adjacent spring.

The combination in a bed spring, of spaced supporting frames, coiled springs interposed between said frames, a laterally eX- tending arm formed on the largest upper convolution of each spring, downwardly bent loops on the ends of said arms overlapping the largest convolution of the adjacent spring, a pluralit)7| ot longitudinally disposed tie wires, and loops formed on said wires and inserted through the loops on the lateral arms and bent under the upper convolutions of the adjacent springs and secured in the arm loops.

3. In a bed spring of the class described, a plurality of coiled springs, means for tying and interlocking the springs transversely and longitudinally, said means cornprising laterally extending arms formed on the largest upper convolution of each spring, downwardly bent loops on the ends of said arms overlapping the largest convolution of the adjacent spring, a plurality of longitudinally disposed tie Wires, and loops formed on said wires and inserted through the loops on the lateral arms and bent under the upper convolutions of the adjacent springs and secured in the arm loops.

4. ln a bed spring of the class described, a plurality of coiled springs, means for tying and interlocking the springs transversely and longitudinally, said means coinprising laterally extending arms formed on the largest upper convolution of each spring, downwardly bent loops on the ends of said arms overlapping the largest convolution ot the adjacent spring, a plurality of longitudinally disposed tie wires, loops formed on said wires and inserted through the loopsv on the lateral arms and bent under the upper convolutions ot the adjacent springs and secured in the arm loops, and bows formed in the tie wires between the loops.

In a bed spring, a series of coiled springs, a laterally extending loop arm on the upper convolution of each spring err-- gaged with the top of the upper convolution of the adjacent spring and having its nose extending downwardly and projecting below the last named convolution, and a wire having a loop for each looparm which wire seats on top of the arm and is disposed
